Citation abstract

To further understand the hepatoprotective activity of Antrodia camphorata in living systems and the possible mechanisms of this protection, the effects of fractions from A. camphorata in submerged culture on the liver and its antioxidative system in acute ethanol intoxicated rats were investigated. The results showed that the ethanolic extract (Fr-I) of A. camphorata was the most effective in the prevention of ethanol-induced acute liver injury and free radical generation in rats. The ethanolic extract administrated prior to ethanol significantly prevented the increase in serum levels of hepatic enzyme markers such as aspartate aminotransferase and alanine aminotransferase. It also normalised the increase of hepatic malondialdehyde concentration and the decrease of glutathione levels in the liver. Moreover, Fr-I improved the ethanol-induced decrease of hepatic glutathione peroxidase and reductase activities. On the basis of these results, the ethanolic extract of A. camphorata may exert its hepatoprotective activity by up-regulating GSH-dependent enzymes and inhibiting free radical formation in the liver.
